Beijing Dispatches Coast Guard Vessels to Diaoyu Islands Amid Tensions with Japan

China has sent its maritime law enforcement into the waters of the Diaoyu islands and unmanned aerial vehicles near remote Japan's territory as China ramps up strains following the Japanese prime minister’s comments regarding the island of Taiwan.

Rights Enforcement Activities

On Sunday, the Chinese coast guard announced that its ships carried out a “lawful patrol operation” through the waters of the Diaoyu islands, which are administered by Tokyo but also asserted as territory by China.

“China coast guard vessel 1307 formation performed surveillance within the territorial waters of the Senkaku islands. This was a lawful patrol operation undertaken by the China coast guard to protect its sovereign claims,” the statement said.

Diplomatic Spat

China and Japan have repeatedly faced off around the disputed territory but the latest activity come amid an intensifying diplomatic spat after the Japan's leader, Sanae Takaichi, told parliament that if China attack the self-governing island of Taiwan it might provoke a armed reaction from Japan.

That provoked a furious reaction from Beijing, which has indicated it demands a retraction from the Japanese official.

Island's Stance

China claims Taiwan as its own territory and intends to annex it under what it terms “unification”. It has left open the military option. Taiwan’s government and people overwhelmingly reject the prospect of Chinese rule – choosing to preserve the current situation without explicitly declaring themselves independent, but pledging to protect their sovereignty if required.

An military assault by Beijing would risk escalating into a regional or global conflict, possibly drawing in the US and other allies including Tokyo, which has territory just 68 miles from the island.

Military Activity

In Taiwan, the defence ministry reported this weekend that it had detected 30 Chinese military aircraft, seven navy ships and one government vessel, which was probably the maritime patrol, active near the island over the past 24 hours.

Official charts released showed up to three drones flying between Taiwan and the Japanese islands off its north-east coast, appearing to go particularly close to the nearby Japanese island. Chinese military transits there are occasional, but infrequent, and Beijing's defense operations in the island's ADIZ generally has been low in recent weeks.

Earlier this weekend, the defense officials said China had been carrying out another “joint combat patrol” to “harass the airspace and sea around us”. It noted Taiwan had sent its own aircraft and ships to track the developments. Taiwan documents these operations a few times monthly as part of what the Taiwanese government says is an ongoing military pressure campaign.

Diplomatic Pressure

Japan has been facing mounting pressure from China since Takaichi made her remarks, with Beijing's diplomatic representative in the Japanese city triggering an official complaint from Japan by stating that “the dirty head that sticks itself out must be cut off”.

China then summoned the Japanese ambassador for the first occasion since 2023, and China’s defence ministry declared that any Japanese intervention would be doomed to fail.

Travel and Education Advisory

Late last week, China cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it did not elaborate.

Three Chinese airlines said on Saturday that tickets to Japan could be cancelled without penalty.

In another escalation, China’s government on the weekend urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an unstable security environment.

While the advice does not amount to a ban, a significant decrease in the population of learners from China could have a detrimental effect on Japanese universities. A historic high of over 336,000 international students were studying in Japan last year, according to education statistics. They featured over 123,000 learners from China – by far the single biggest group.

Media Response

Earlier this weekend, a official press commentary charged the Japanese official with performing a political stunt that was “not just dangerously provocative but fundamentally perverse”.

“A conflict between Japan and China would not be a limited skirmish; it would likely draw in other powers, including the United States, and could rapidly escalate to a major confrontation with severe repercussions.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Japanese leaders have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the US.

Nevertheless, China’s ruling Communist party says the unification of Taiwan with the People’s Republic of China is “unavoidable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, China has also been escalating its non-military activity and its statements towards the island.
